Lighting is a source of illumination, a fundamental necessity in modern life. It is used to provide both functional lighting in workplaces, homes, and other structures and ambient lighting in different tones and colors at recreational, cultural, and other venues. Lighting is divided into two primary categories- natural lighting and artificial lighting. Natural lighting is derived directly from the sun, moon, or other natural light source. Artificial lighting is generated in various forms using lamps and fixtures, such as fluorescent, LED, and halogen lights. Different kinds of lighting are used in various applications. LED lighting is a popular option for both outdoor and indoor lighting because it is energy-efficient, durable, and long-lasting. Halogen and fluorescent lighting are also commonly used, especially in industrial and large commercial spaces. Lighting plays a fundamental role in strengthening communities. It can improve visibility for safety and reduce the risk of crime. Softer, warmer lighting can help to evoke a relaxed or intimate atmosphere in restaurants, bars, and other settings. In conclusion, lighting is a fundamental element of modern life. It is used to provide both functional and ambient applications that keep people safe, healthy, and more at ease.
